Unusual Aluminum U-Channel?

I have a new product line in mind for ScopeRoller, and I need to make what is effectively a U out of sheets of 1/4" thick aluminum.  But it struck me that it would be faster to buy U-channel aluminum extrusions and cut them into 1/4" thick slices (perhaps machining them for evenness and dimensions).  What I would need, however, would be a U-channel that was 1/4" thick, with a 1 1/8" gap, and the legs would be 2-3" long.  That's an unusual size for a U-channel extrusion.  Any suggestions for an industry that uses something like that?



    McMaster Carr is your friend.

  2. It took some hunting, but seems the closest match: it would give me something that would have a space 1.25" wide. I actually need 1.125" wide. I could use, but then I would have to machine out the slot, and the leg length is a bit shorter than I want. It's a good start. I will probably machine what works, then figure out the closest approximation by slicing some channel.

  3. Do they have some flat tubing that will give the right dimensions if you saw off one short side? I have vague memories of having seen some of what was essentially a hollow aluminum bar.
